‘A’ is 6 years younger than ‘B’ and 7 years elder than ‘C’. If the present age of ‘B’ and ‘D’ is 25 years and 10 years, respectively, then find the ratio of present age of ‘C’ to present age of ‘D’.
Present age of ‘A’ = 25 – 6 = 19 years Present age of ‘C’ = 19 – 7 = 12 years Required ratio = 12:10 = 6:5
